Abstract: Nano-Ni was first used as catalyst for disproportionation of resin acid. The main factors affecting disproportionation of abietic acid were investigated, such as stirring rate, the category and quantity of catalysts, temperature, quantity of solvent, etc. The optimum conditions for disproportionation of abietic acid over nano-Ni were determined as follows: stirring rate 300 r/min, reaction temperature 160℃,dosage of catalyst 2.0% of abietic acid, 200# solvent oil 50%(weight) and reaction time 3 h.

Key words: resin acid, rosin, nano-Ni, catalysis, disproportionation
